In this paper,a fuzzy methodology is proposed to optimize network bandwidth allocation with demand uncertainty in communication networks (CNs).In this proposed methodology,uncertain traffic demands are first handled by a fuzziflcation way. Then a fuzzy optimization methodology is presented for network bandwidth allocation problem with the consideration of the trade-off between resource utilization and service performance in CNs. Accordingly,the optimal network bandwidth is allocated to obtain maximum network revenue in cNs.Finally,a numerical example is presented for purpose of illustration.
